Thanks Doru, That solves it! A quick and clean fix :-).

Hi, I am not quite sure I understand your problem, but I believe what you want is to only react to a change in a text. This information is placed in the #text port. Here is a basic example of how to react to it: http://ws.stfx.eu/ETEC2JH7363M Cheers, DoruOn Feb 6, 2017, at 2:16 AM, Offray Vladimir Luna Cárdenas <offray.l...@mutabit.com> wrote: Hi, For my Grafoscopio notebooks, I have implemented a way to auto-updating the content of a node, so it is automatically saved in the notebook when a node content is changed. The problem is that a node contains an embedded playground that produces text as output when executed (for example the playground reads a file or scraps HTML or calculates a hash), the text of the playground is replaced with the executed output. If the playground produces a visualization or non-textual output, this doesn't happen. I imagine that the source of the problem is here: ======= GrafoscopioNotebook >> autoSaveBodyOf: aNode body body class = TextModel ifTrue: [ body body whenTextChanged: [ :arg | aNode body: arg ] ]. body body class = GlamourPresentationModel ifTrue: [ | playground | playground := body body glmPres. playground when: GLMContextChanged do: [ :ann | ann property = #text ifTrue: [ | playgroundText | playgroundText := (playground pane ports at: 2) value. aNode body: playgroundText ] ] ] ======= as you can see the "when: GLMContextChanged" updates a node body with the playgroundText, as intended, so I can capture any change of the playground code, but I would like to add some condition to **not** update the body content if the text is the result of a playground execution. There is any way to do this? Thanks, Offray-- www.tudorgirba.com www.feenk.com "If you can't say why something is relevant, it probably isn't."
